Volumetric shoe sizing

Abstract

Techniques for automated shoe fitting are disclosed. The present disclosure includes a method including receiving foot data including information about a foot of a user (e.g., user preferences, images, other information), generating a foot model of the foot based on the foot data, where the foot model includes a three-dimensional model, comparing the foot model to a shoe model, where the shoe model includes a three-dimensional model, and displaying individualized shoe information to the user based on the comparison for the user to choose an effective shoe fit. In some examples, the present disclosure describes determining three-dimensional characteristics of a shoe (e.g., via an interior scan), determining shoe data and characteristics (e.g., material characteristics), generating a shoe model, determining parameter ranges for the shoe, and rendering the shoe model. The disclosed technology can prioritize user agency and/or can generate recommendations.
